TI Dragon (!)

As residential students, we sometimes get bored. And at those times, we get to be more creative than usual. Like in this photo, one of my residence friends came up with this shape. For me it seems like a bat. However, for Ekin, who is the one who had nothing to do but this :), it is more like a dragon with a tail (!). The most shocking thing is he did this only with the equations we have learned in the math class.
